MACHINE FOR SHAPING AND CUTTING DO UGH.

SPECIFICATION forming part of Letters Patent No. 530,582, dated December 1 1, 1894.

Application filed May 24,1894. Serial No. 512,263. (N model.)

' To aZZ whom it may concern.-

Be itknown that I, FRITZ DiiHRKoP, of New York city, New York, have invented all Improvement in Machines for Shaping and Outting Dough, of which the following is a specification.

This invention relates toa machine forforming fermented dough into cylindrical bodies and cutting such bodies up into short lengths,

\ so quickly that the blade does not interfere with the continuously moving body of dough.

In the accompanying drawings: Figure 1 is a side elevation partly in section of the machine; Fig. 2, a vertical section on line 2, 2,

Fig. 1; Fig. 3,a horizontal section on line 3,

a 3, Fig. 2; Fig. 4, a horizontal section on line 4, 4, Fig. 1; Fig. 5, a sectional top view of the knife-operating mechanism; Fig. 6, a hori- ,zontal section of part of the same; Fig. 7, an

elevation, partly in section, of the collars g, i,- Fig. 8, a side view of Fig. 5, and Fig. 9 a perspective view of a modification of the knife.

The letter a, represents a shell or vessel into which the dough is thrown andwhich is provided, at its lower end, with a discharge nozzle a, that delivers the dough A upon an endless feed apron b. This apron passes over a pair of rollers, of which the roller 11', driven from the power shaft is shown. In order to feed the dough out of nozzle 0., there is hung within vessel a, a conveyor screw 0, which receives motion from power shaft 0, by worm c and worm wheel 0 which is mounted upon the shaft 0 of the conveyor screw.

The dough delivered upon the apron b, is

cut into the lengths required for forming a loaf of bread or a roll, by a vertically reciprocating blade or cutter d, guided in slotted by such spring.

nates at its lower end in a toe f This too is engaged by aroller g, pivoted .to a lug 9 of a loose collar g, (Fig. 1,) surrounding horizontal shaft h. This shaft is revolved by a cone pulley hfifthat is connected to a cone pulley c of power shaft 0', by belt 0. Op posite to the loose collar g, the shaft h, carries a fixed collar 1', having a beveled notch 2'. (Fig. 7.) This notch is adapted to be engaged bya'beveled spring bolt g sliding in perforation g of collar g. Normally the bolt 9 engages the fixed collar i, and thus the loose collar 9, is revolved by shaft h, to reciprocate the rod f, and consequently the cutter d.

t In order to make the motion of cutter d, not uniform but intermittent, I withdraw the bolt 9 from the fixed collar 2', for a short time during each revolution of the shaft, and

thus arrest the motion of the cutter between its descents. ing manner: The shaft h, is provided with a fworm 71, engaging a worm wheelj, mounted This is efiected in the followupon the shaft b of roller 1). Upon this shaft isalso mounted the grooved rollerj', which is adapted 'to operate a sliding rod is, when the latter is held against it by friction clutch or roller m. The-slidingrod k, is prov-ided with a forked cross-piece 70', which straddles a fixed guide rodk This guide rod is engaged by a vertically adjustable collar it, having clamp screw k by which the position of the collar, and consequently the stroke of the slide may be regulated. A spring 70 secured to cross-piece lo, and to shell a, serves to normally draw the slide upward. The rod 75, is adapted to be held and clamped against the roller j by means of the roller m, pivoted to lever m, which turns on pivot m The upper end of the lever m, is

connected to a spring m which tends to force the roller m against slide is, and the latter against roller j (Fig. 2). In this way the, revolution of roller j, when engaging the rod is, will tend to draw the same down against the action of its spring 7%, while when the rod becomes disengaged, it will be drawn up The lever m, is oscillated at each revolution of shaft h,by the lug g, of loose collar g. This lug engages a bail m of lever m, (Fig. 8) which is provided with a seat or notch m At each revolution of the shaft h, the lug will upon leaving its seat m vibrate lever m, by means of the bail m to take the friction roller 'm, off the roller j and release the slide 70, la, which will now be drawn up by its spring. When upon the further revolution of the shaft h, the lug 9 reenters its seat m thespring m will vibrate lever m, to clutch the slide 1c 70, between rollers mj, and in this Way the slide is again lowered. The cross piece it, of the slide, when arriving at its lowermost position,

strikes against one arm of a lever 72, turning on pivot n. The other end of this lever opcrates by a rod 02 a pivoted spring finger n (Fig. 1,) having a beveled edge a adapted to engage the spring bolt g This lever, when lowered by means of rod n is interposed within the path of the spring bolt, and will push the same away from the fixed collar e', and back into the movable collar 9. Thus the movable collar is disconnected from the fixed collar and its motion is arrested until the withdrawal of the finger, by vibration of lever a, when the bolt is free to shoot forward and into re-engagment with the fixed collar. In this way the stroke of slide, 70 70, by the movement of lever n, and finger n determines the pause between the strokes of the cutter d.

It will be seen that by the above described mechanism, an intermittent feed is imparted to the cutter, so that it remains at rest above the feed apron, for a sufficient time to permit the dough to be fed forward upon the apron. When the proper length of dough has been thus fed forward, the cutter descends with great rapidity, so as not to interfere with the continuous forward motion of the dough. By setting the collar 70 the stroke of the slide 7t, 7t, and consequently the motion of lever a, may be adjusted, to adjust the play of finger a and to thus shorten or lengthen the intervals between the descents of the cutter. In this way long and short sections of dough may be severed from the main body, to form bread and rolls of various sizes.

In Fig. 9, the discharge nozzle a, of shell a, is made flat, and the cutter d, is provided with a series of parallel longitudinal blades 01 In this way, a wide and flat strip of dough may be cut up simultaneously into transverse and into two or more longitudinal sections, to form a number of rolls by a single cut.

substantially as described;

2. The combination of a vessel having-adischarge opening with a conveyer, a feed apron, a uniformlyreciprocating cutter above the apron, and a single adjustment stop movably supported upon the machine and provided with means for securing it in any one of the positions of its movement, which alone by its position determines the length of the intervals between the strokes of the cutter, substantially as described.

3. The combination of a vessel with a con- Veyer, a feed apron, a low speed shaft for operating the latter, a high speed shaft driving the apron shaft, a cutter reciprocating to and from the apron having intermittently an op erative connection with the high speed shaft to reciprocate it in one direction, to obtain a quick stroke of the cutter, and means for reciprocating it in the" opposite direction, the cutter being stationary for a period between the complete reciprocations, substantially as described.

4. The combination of a vessel,with a conveyer, a feed apron, a low speed shaft for operating the latter, a, high speedshaft driving the apron shaft, a cutter reciprocating to and from the apron, having intermittently-an operative connection with the high speed shaft to reciprocate it in one direction, to obtain a quick stroke of the, cutter, and means for-reciprocating it in the opposite direction as shown, the cutter being stationary fora period between the complete reciprocations, and meansfor regulating the length of the stationary period, substantially as described.

, 5. Thecombination of a vessel, with 'a con- Veyer, a feed apron, a cutter reciprocating upon and away from the feed apron having an intermittent operative connection with thedriving mechanism of the machine for producing such reciprocation, and means. independent of the operative mechanism for varying the stationary period between such reciprocations, substantially as described.

6. The combination of acutterwi-th an operating lever, a rod f,a shaft h, a fast and loose collar upon the same, a spring bolt adapted to connect the collars, and a roller 9', adapted toengage rod f, substantially as specified.
